/ˈvɔɪd æb ɪˈnɪʃioʊ/

Definitions

  1. (adj.) Having no legal effect from the outset; treated as invalid from the beginning.

  2. (adv.) From the very beginning; with nullity attaching from inception.

Commentary

Used primarily to indicate that a legal act or contract is invalid from its inception, not merely voided later. Important to distinguish from voidable, which is initially valid but subject to annulment.
